Why would she be upset if you’re paying the money while she continues to drive the rental and allow you to keep the miles down? It sounds like she’s trying to weasel her way in and control you…..I’d be more like take the $200 or walk, your choice. I have rented cars for trips instead of taking my own car to reduce wear and tear. Makes perfect sense to me, so there must be some ulterior motive there.

After thinking about it, it’s a $hit test to see if your car is more important than she is. However it’s a conflation of two different things and how you solve her money issue clearly doesn’t have to involve you letting her use your car or making you drive a car you hold dear.

You may want to re-evaluate your long term prospects with this person. If something small can create an issue, image what marriage will do after she gets half your 335i in a divorce. Been there done that, let me save you the pain.
